USAGE: gradle [option...] [task...]
-?, -h, --help Shows this help message.
-a, --no-rebuild Do not rebuild project dependencies. [deprecated]
-b, --build-file Specify the build file.
--build-cache Enables the Gradle build cache. Gradle will try to reuse outputs from previous builds.
-c, --settings-file Specify the settings file.
--configure-on-demand Configure necessary projects only. Gradle will attempt to reduce configuration time for large multi-project builds. [incubating]
--console Specifies which type of console output to generate. Values are 'plain', 'auto' (default), 'rich' or 'verbose'.
--continue Continue task execution after a task failure.
-D, --system-prop Set system property of the JVM (e.g. -Dmyprop=myvalue).
-d, --debug Log in debug mode (includes normal stacktrace).
--daemon Uses the Gradle Daemon to run the build. Starts the Daemon if not running.
--foreground Starts the Gradle Daemon in the foreground. [incubating]
-g, --gradle-user-home Specifies the gradle user home directory.
-I, --init-script Specify an initialization script.
-i, --info Set log level to info.
--include-build Include the specified build in the composite. [incubating]
-m, --dry-run Run the builds with all task actions disabled.
--max-workers Configure the number of concurrent workers Gradle is allowed to use. [incubating]
--no-build-cache Disables the Gradle build cache.
--no-configure-on-demand Disables the use of configuration on demand. [incubating]
--no-daemon Do not use the Gradle daemon to run the build. Useful occasionally if you have configured Gradle to always run with the daemon by default.
--no-parallel Disables parallel execution to build projects. [incubating]
--no-scan Disables the creation of a build scan. For more information about build scans, please visit https://gradle.com/build-scans. [incubating]
--offline Execute the build without accessing network resources.
-P, --project-prop Set project property for the build script (e.g. -Pmyprop=myvalue).
-p, --project-dir Specifies the start directory for Gradle. Defaults to current directory.
--parallel Build projects in parallel. Gradle will attempt to determine the optimal number of executor threads to use. [incubating]
--profile Profile build execution time and generates a report in the <build_dir>/reports/profile directory.
--project-cache-dir Specify the project-specific cache directory. Defaults to .gradle in the root project directory.
-q, --quiet Log errors only.
--recompile-scripts Force build script recompiling. [deprecated]
--refresh-dependencies Refresh the state of dependencies.
--rerun-tasks Ignore previously cached task results.
-S, --full-stacktrace Print out the full (very verbose) stacktrace for all exceptions.
-s, --stacktrace Print out the stacktrace for all exceptions.
--scan Creates a build scan. Gradle will emit a warning if the build scan plugin has not been applied. (https://gradle.com/build-scans) [incubating]
--status Shows status of running and recently stopped Gradle Daemon(s).
--stop Stops the Gradle Daemon if it is running.
-t, --continuous Enables continuous build. Gradle does not exit and will re-execute tasks when task file inputs change. [incubating]
